Hi Fred,
I am just posting since we know each other through Stu.
I consider keylight buggy anyway. I use it to create mattes and fills separately and almost never use the final result inside of keylight since most of my work includes several custom mattes and masks to get the comp and keys to look their best. Much of my matte work and keying for that matter is outside of Keylight. I do use it to color correct my fills sometimes as well but often creating a perfect matte is a combination of mattes generated with keylight as well as other keyers and custom masks. Just sayin’,,,
cheers,
-Jon
